She said: “Right now, I don’t imagine that I would go that route. But I’ve learned to never say never.”

And the glamorous mum-of two revealed that she can't wait for her daughters Malia and Sasha to have children.

She admitted she wants to be the same supportive grandmother like her own mother has been to her daughters.

She said: "I want to be that grandma. But I also might still be peaking.

"I'll have to balance it all -being a good grandma with doing the work I care about."

The first lady plans to help her daughters "achieve their dreams" but that doesn't mean she'll be slowing down at 70.

She insisted the "having it all" debate doesn't have an expiry date.

In a new interview with People Magazine Michelle also talks about her plans for the future when the Obamas will leave the White House after 8 years in 2017.

Michelle revealed: “I will be in my early fifties when I leave here and I have so much more that I should do.

“I don’t have the right to just sit on my talents or blessings.”

The mum-of-two, who worked as a high-flying lawyer before leaving to help her husband become President added that “the sky is the limit” on what she plans to do when she leaves the White House.

When asked which women in their 70s and 80s she most admired, the first lady praised 80-year-old actress Cicely Tyson, who starred in Broadway’s “The Trip to Bountiful” last year and 76-year-old actress Jane Fonda.

And of course Mrs Obama didn't forget her own mother, 76-year-old Marian Robinson.

Michelle said: “She speaks her mind.

“She does exactly what she wants to do every single day without apology. I’m not there yet, but I look forward to that.”
